TYPOGRAPHICAL OR SLUG CASTING MACHINE.

Application filed May 3, 1915 Serial'No. 25,510.

To all whom it may concern: 7

Be it known that I, JOHN -W. GRAHAM, a citizen of the United States,residing at Hinton, in the county of Summers and State of West Virginia,have invented certain new and useful Improvements in Typographical orSlug Casting Machines, of which the following is a specification.

' My invention relates to typographical or slug casting machines, suchas linotypes of the original construction; wherein, circulating matricesare released from a magazine in the order in which their charactersareto appear in print, and then assembled in line together withexpanding spacers; the composed line brought in contact with the face ofa mold; the mold filled with molten metal to form a line of type or slugagainstthe matrices, which produce the type characters thereon, and thematrices thereafter returned to the magazine from which they wereoriginally drawn. a

More particularly it relates to that class of machines having a seriesof magazines,-

any one of'which can be shifted into operative position, and wherein;the magazines are individually removable and exchange able, and, to thatend are mounted in a basket or rack support; and wherein, magazine isprovided with an individual escapement mechanism consisting of vergesand a slotted bar in which the verges are housed and suchescapementmechanism is made fast to the magazine.

In the drawings I have shown the invention as applied to linotypemachines, but obviously, it may be applied to other machines, such astypesetters, and typecasters,

and many changes and variations may be made therein, without departingfrom the spirit of the invention. or the principle thereof. Generallyspeaking I desire to be under stood thatI do not limit myself to anyspecific form or embodiment, except in so far as such limitations arespecified in the claims.

Referring to the drawings, Figure 1 1s a side view of a portion of alinotype machlne having my invention applied thereto. Flg. 2 is afrontal and side 'elevation'view of the cog gear and worm gear A Fig. 3is'a view of the rollers, cogs andsprocket, that are used in the powerraising and loweringdevice.

nism for raising and lowering the basket or rack. Fig. 5 is a side viewof a section of" rack or basket showing the escapement mechanism. Fig.6is. a side view of the key board mechanism. Fig. 7 is a view of amagazine looking at the bottom, showing the bar to house they verges andalso the strengthemng bars. Fig. 8 is a perspective view of a section ofa magazine resting on its angle iron support and showingthe dog, whichholds the magazine'in place. is a rear viewof a basket.

Referring to Fig. l 3 A represents aside view of the main-arm or framewhich supports the basket or rack. V a circle, and the basket or rackwhich travels on this arm, travels with a circular motion. The basket,at the front and rear endsfthe arm A, and the guide plates B are 7 allformed in the arcs of I circles, such cir-. cles havlng a common center;thus the motion of the basket is the same as if it were sufficientlyforward to be a common center Fig. 9 y,

This arm is formed in the arc of for. all of these circles, but, bysuspending the basket to the arm A, we accomplish the desired resultwithout putting any of the mechanism in the way of the operator. It isalso apparent to those skilled in the art, that the front and rear endsof the magazines come into operative position at the same time. i

A represents an arm attached to the main arm A, at each side andextending back to support the distributing mechanism, this arm is offsetat its point of connection with the arm'A, toallow the piece B to passbehind it.

i A represents a cog gear immediately be hind the worm gear wheel, A(SeeFig. 2.) The gear Wheel A .carries thepiece B 7 A represents a, wormgear wheel intermeshing with the worm} thread on the shaft A i Arepresents a shaft having at itsv uppermost end a-worm thread, and atits lower end a bevel gear.

A represents a brace to strengthen the main arm A. There are two ofthese braces, one at each side ofthe forked arm A.

B represents the basket or rack, in which the magazines are housed.

B represents the 1ron straps which pass up the sides of the basket atits ends, and

to which the individual baskets are made fast; these strapsalso rub onthe inside of the arms A, and the braces A to guide the travel of thebasket.

B represents a strap which travels on the cog gear A and is bolted tothe guide bar B B represents the guide bars which are securely affixedto the basket and travel on the main arm A. These guide bars B? arebored out near their ends, and have housed in these sockets, the rollersB B represents rollers set in guide bars, as mentioned above.

B represents an angle iron, one side of which is affixed securely to thestraps B at both ends of the basket, and to the guide bars B near thecenter of the basket; the other angle of this angle iron projectsintothe inside of the basket, at right angles, thus forming the support forthe magazines. These angle irons on the inside of the basket work inpairs, one on each side, and are lined on their bottom, full length,thus giving the basket theappearance of a box containing a series ofshelves, all converging toward their frontal'point, at the same degree.The object of this lining is to support the magazine when it is pulledback, to be taken out. The magazine being narrower at its frontal endthan at its rear end, would drop through at the back, but for thislining. This lining is shown by the line B, in Figs. 8 and 9.

13 represents a dog fitted on the inside of the angle irons B, near thelower, or escapement end of the basket. Its function is to hold themagazine in place. Its construction is suchas to hold the magazine fromslipping endwise in the basket and it also holds the magazine down inplace.

(See Fig. 8.)

Fig. 2 shows front and side elevation views of the cog gear A and. itsconnected worm gear wheel A".

F ig.3 shows the rollers,gears and sprocket of the power raisingmechanism, with the casting Z removed.

I) represents a roller set stationary below the belt E. Its function isto hold the belt E up in place when the rollers F or G are thrownagainst the belt E, to operate the power raising or lowering device;

' E represents the belt from which power is generated to operate thepower raising and lowering device.

F represents the rubber covered roller of sufficient width to cover thewidth of the belt E and having behind, and. made fast to it, the coggear F G and G are exact duplicates of F and F I represents a cog gear,made fast to the sprocket J and of a width the same as F and G1.

J represents the sprocket mentioned above.

Z represents the casting which houses the rollers, gears and sprocketused in the power raising device. It is pivoted on the pin Z which isset securely in the frame of the machine. It is connected at itsuppermost end to the strap L which in turn is connected to the lever L.The rollers F and G with their connected cog gears F and G are housed onpins made fast to the casting Z, while the sprocket J and its attachedgear wheel I are housed on the pin Z The gear wheel G is intermeshedwith the gear wheel F and the gear wheel F also intermeshcs with thegear I, but the gear G does not intermesh with the gear I.

In operating the power mechanism, when the lever L is moved inwardsufliciently it rocks the casting Z on the pivot Z and forces the rollerG against the moving belt E, which belt E operates the roller G and itsconnected gear wheel G G is intermeshed with F and thus operates it. Fis intermeshed with the gear I, made fast to the sprocket J, and thusthe sprocket J is operated. The sprocket J operates the shaft K by thesprocket chain M and the sprocket K, on the shaftK The shaft K operatesthe screw shafts A by means of intermeshed bevel gears and the shafts Aoperate the worm gear wheels A and their attached cog gears A, thusoperating the basket upward or downward by means of the piece B Toreverse this motion the hand lever L, is moved outward sufiiciently tothrow the roller F against the belt E and this operates the roller F andits attached gear F F operates the gear I being intermeshed with it andI being fast to the sprocket J operates it, and the power is transmittedas above. Fig. 4 represents a back view of the forked arm A. This viewshows the shaft K with its sprocket and bevel gears and the screw shaftsA attached to the arm A.

Fig. 5 is a side view of a section of a basket with a section of thestrap B cut away; also a. section of angle iron magazine support B cutaway; also section of theside of the magazine cut away to show thematrices X in place, held by the verge V; also shows the reinforcing barslotted to receive the spring P, and also shows trip finger Q, connectedto the key rod Q Fig. 6 shows a side view of the key board mechanism.

. represents a key.

Q shows key bar.

Q shows pin on which key bar is pivoted.

Q shows rod to trip the dog R.

B shows leg of the dog R.

B shows rod housing the cam R R shows rubber covered rollers.

R shows spring to hold key rod down.

In operation, when the key Q is pressed it raises the rod Q which movesthe dog It and allows the leg R to pass into the slot rod R and notresting on it as in my machine. When the key Q? is pressed it raises therod QF, in turn operating the dog R, allowing the rod R to drop, but thekey rod Q does not drop, but being suspended above the rod R it remainsstationary.

When the rod R drops, the cam R comes in contact with the movingroller Rand when the cam rolls over to its highest point it raises the rod Rsufficiently to raise the key rod Q and the key rod comes in contactwith the verge V and trips it, allowing the matrix to escape. In mymachine as soon as the key is touched the key rod drops and trips theverge, allowing escapement of the matrix and as the mechanism is movingto restore the rod Q to its place, the operator may betouching anotherkey'and no time is lost. Operators listen at all times to hear thematrices drop, so by the old method the operator has to wait until theoperation of keyboard mechanism is complete, before he hears the matrixdrop, while in my machine the matrix drops almost instantaneously andthe operator can operate another key while the mechanism is readjustingitself. This improvement greatly increases the speed of the machine.
